1st Quarter FINAL Flashcards
describe the deciduous forest biome
yearly rainfall = 75-125 cm, avg temp = 28 degrees C in summer, 6 degrees C in winter, plants = woody shrubs, ferns, mosses, animals = rabbits, bears, snakes, wood peckers.
describe the coniferous forest (taiga) biome
yearly rainfall = 35-75 cm, 14 degrees C in summer, -10 degrees C in winter, plants = evergreen trees, animals = squirrels, finches, chickadees, jays, elk, moose, etc.
describe the tropical rainforest biome
most biological diversity out of any biome, up to 400 cm of rainfall, 34 degrees C during day, 20 degrees C during night, animals = live in canopy, toucans, monkeys, butterflies, etc.
describe the grassland biome
rainfall = 25-75 cm, summer = 30 degrees C, winter = 0 degrees C, animals = praire dogs, mice, bison
describe the desert biome
less than 25 cm of rain, avg temp = 38 degrees C in summer, 7 degrees C in winter. Deep rooted plants, kangaroos, jack rabbits, spadefoot toad, etc.
where is mono lake?
california
why is mono lake important to migrating birds? (3)
acts as an ancestrial breeding ground, important stop for migrating birds to eat, safe place for birds to lay eggs because it’s away from predators
Why is mono lake so salty?
water from tributaries was taken away and given to LA as the climate got dryer (check)
top consumer at mono lake
coyotes
producers of mono lake
planktonic algae, benthic algae
how did charles darwin come up with famous theory
During his voyage on the Beagle, he investigated many animals that developed his theory of evolution, like finches.
do individuals evolve?
no. populations evolve.
example of mutualism
clown fish and anemone; clown fish goes in anemone and hides from predators, anemone is protected from butterfly fish in return
example of commensalism
Remoras attach themselves to sharks and feed on the food they leave behind.
example of parasitism
tic feeding on dog blood, wasp laying eggs on caterpillar so babies can eat the caterpillar when they hatch
all zones of ocean
intertidal, neritic, oceanic, benthic
describe the intertidal zone
ocean meets land/exposed to air for part of day. organisms have adaptations to survive waves and air. ex = sea grasses, periwinkle, snails, herons
neritic zone
after intertidal, deeper, ocean floor slopes. ex = plankton, seaweed, sea turtles, dolphins, corals, sponges
oceanic zone
sea floor drops sharply, plankton, whales, fishes, sharks, some organisms live in very deep water and feed on material sinking from surface
benthic zone
ocean floor, deepest parts = no sunlight, very chilly. fishes, worms, crabs with special adaptations to survive deep, dark water. eat organisms that sink and some get energy from thermal vents on ocean floor (ex: bacteria)
what is the thermocline?
300-700m below sea level, temp sharply drops at a rate much faster than other two zones
all ocean temperature zones
surface (100-300), thermocline (300-700), deep (700-bottom)
amounts of calories in a Calorie
1000
order of eras from current to oldest
cenozoic, mesozoic, palezoic, precambrian.
